Claims.

An object of the present invention is to provide means in connection with a slug-rejecting structure for enhancing the effectiveness and positive operation thereof to reject slugs of various kinds.

More specifically, an object of the invention is to provide the coin-receiving aperture of a coin slide with a wrench or grip, whereby a chisel dog may more effectively intercept and stop the entry of a slug into the coin-operated release mechanism of a vending machine.

The foregoing and other objects are attained by the means described herein and disclosed in the accompanying drawing, in which:

Fig. 1 is a plan view of a coin slide structure embodying the invention.

Fig. 2 is a side view of the Fig. 1 device.

Fig. 3 is a plan view of a double-acting ratchet member or pawl which cooperates with notches formed along one side edge of the slide.

Fig. 4 is a fragmental plan view of the slide or actuating member.

Fig. 5 is a cross-sectional view taken on line 5-5 of Fig. 4.

The means of this invention is designed to preclude improper operation of a coin slide structure such as is applied to vending machines, and to preclude jamming and possible injury to the structure by reason of the insertion of slugs therein. Like the device of my aforesaid copending patent application, the present device includes a slug cutter which dents or shaves the slug edge so that said cutter or other parts of the mechanism may move into position for precluding a full operative stroke of the handle member or actuator. It is to be understood that the present device may include the same means to eject all slugs or improper coins as set forth in my aforesaid copending application, supplemented, however, by the improvement described hereinafter.

' The present improvement will of course be found applicable to other forms of coin slide structures which include cutters or dogs that operate upon the edges of the coins or slugs, as will be apparent.

In the drawing, l2 indicates a guide member or plate which has suitable longitudinal bearing or guide channels i3 and [4 for slidably receiving the side edges I5 and iii of a coin slide or coin advancing member IT. The member I! prefer- 5 ablyis in the form of a substantially flat longitudinal strip having the forward handle end l8 and a rear end IS. The coin slide is adapted to be advanced from the inoperative extended position of Fig. 1 to a fully advanced position, (to

be described later), at which the handle end is disposed a short distance from the mounting plate 20, and at which position the coin is delivered by the slide to any suitable receiver or till at the right-hand side of the mounting plate. The guide member I2 will be seen to extend both forwardly and rearwardly of the mounting plate 20.

In the normal or inoperative position of the coin slide, (Fig. 1), an aperture 2| therein, for the reception of nickels, registers substantially with an exposed cut-away portion 22 of the part I2 so that such coin may be placed within the aperture 2!, and be advanced by the slide while resting upon the bottom wall 23 of the guide plate or member l2. the bottom wall 23 to enable the operator to easily remove a coin inadvertently placed in the opening 2i, before advancement of the slide to an appreciable extent.

It is of importance to note that the aperture 2| of the slide is located off-center, (Fig. 3), and that it has a mouth or cut-out at the edge l6 of the slide bounded by a pair of opposed abutments 25 and 26. Abutment 25 is a dog stop, and is formed In part by the edge l6 of the slide. The abutment 26 is a dog guide, and is located inwardly of the slide edge IE but associated therewith, in a sense, by reason of the connecting incline or track portion 21. The distance between the abutments 25 and 26 is less than the diameter of aperture 2 I. The abutments are adapted to cooperate with the stop end 28 and the chisel or cutter part 29 of a slug intercepting dog 30, in a manner to be described later.

Reference is made to the copending application above noted, for details of the mechanism for ejecting the coins at the rear of the device, as that portion of the mechanism is not necessarily included in the present invention. For the same reason, a detailed description concerning the magnet 3|, and the coin slide pawl or ratchet means 323334-35, need not be given except to state that the pawl or ratchet means functions to permit but one complete reciprocation of the slide H for each proper coin inserted in the opening 2|.

The trigger member 36 which is pivoted upon a bracket 31 of the top plate 38, as indicated at 39, has a vertically movable nose 40 adapted to enter the holes in washer-like slugs, or the open- A finger hole 24 is provided in 2 ing 2| when no coin or slug is present, to preclude full advancement of the slide as explained in detail in the copending application.

In accordance with the present invention, the coin receiving aperture 2| of the slide I! is provided with friction means, preferably, though not necessarily, in the form of serrations or toothgrips 4| disposed approximately diametrically opposite to the dog guide or abutment 26. The grips or wrench elements 4| may be sharpened or not, as desired, and they perform the function of precluding rotation of a slug or improper sized coin when the chisel edge of the dog 30 engages such slug or improper coin. The chisel edge of the dog thereby assuredly dents or shaves the edge oi the improper coin or slug and jams it to preclude full advancement of the slide. The teeth or grips 4| may be formed during the operation of punching out the opening 2|, or they may subsequently be formed in the opening. In any event they perform to frictionally hold a coin or slug, as follows.

The dog 30, which is pivoted upon the body of the device as at 42 in the plane of slide H, has a flat guiding portion 43 which normally rests against the side edge iii of slide IT with the result that the stop end 28 of the dog is held out of the path of movement of the slide abutment 25. As the slide is advanced, however, the dog element or guide 43 slides inwardly over the incline 21, due to the yielding action of a spring 44, to place the abutment 28 of the dog in position to engage the abutment 25 of the slide and to thereby arrest the advancing movement of the slide. The foregoing described action results when no coin or slug is placed in the coin slide aperture 2|.

When a proper sized slug of cardboard, lead, or other comparatively soft material is placed in the receiving aperture 2|, and the slide is advanced by the operator, the cutter point or chisel edge 29 will move inwardly over the incline 2'? and will dig into, shave, or indent the edge of the soft slug thereby permitting the stop end 23 of dog 30 to move into arresting engagement with the abutment 25 of the slide member 117. During the digging, shaving, or indenting of the slug by the chisel edge of the dog, the slug is precluded from rotating in the aperture 20 by reason of the friction or gripping means 45 thereby avoiding all possibility of the chisel edge to over-ride the edge of the slug and permit its passage into the mechanism of the device.

When a proper coin is placed within the aperture 2i, advancement of the slide causes the abutment 43 of the dog to ride over the periphery of the coin edge, thereby maintaining the stop end 28 out of the path of movement of the slide abutment 25. A coin smaller than the proper one naturally will not extend from the open edge of the receiving aperture 2! sufliciently to force the guide 43 outwardly and remove the stop 28 from the path of the slide abutment 25.

Perforated, thin, or magnetic coins or slugs are rejected by the dog 40 or magnet 3!, as explained in the aforesaid oopending application.

What is claimed is:

1. As a new article of manufacture, a coin slide for coin controlled devices, comprising a straight substantially flat longitudinal plate having front and rear edges, a plurally notched longitudinal side edge on the plate, said notches being of uniform depth, the endmost ones of the plurality of notches being longer than the intermediate notches, a second side edge on the plate in substantial parallelism with the first mentioned side edge, said second side edge being cut away intermediate the front and rear edges to provide an open sided coin-receiving aperture, a transverse abutment at the forwardportion of said aperture, an incline adjacent to the rearward portion of said aperture, and means associated with said coin-receiving aperture to resist rotational movement of a coin-shaped slug therein.
